Problem summary
**************************************************************** * USERS AFFECTED: IBM WebSphere Application Server Full * * Profile versions 8.0, 8.5.5, and Liberty * * Profile version 8.5.5 users of * * WebContainer. * **************************************************************** * PROBLEM DESCRIPTION: The ServletRegistration.getMappings() * * might return null instead of an empty * * collection. * **************************************************************** * RECOMMENDATION: * **************************************************************** When the javax.servlet.ServletRegistration.getMappings() method is called before any servlet mapping is added, a null value is returned since the list has not been initialized
Problem conclusion
The WebContainer code was modified to return an empty collection. A new WebContainer custom property needs to be set to enable the behavior provided by this APAR: Name: com.ibm.ws.webcontainer.emptyServletMappings Values: true/ false (default) Please refer to the following technote for instructions on enabling WebContainer custom properties: Full profile: http://www.ibm.com/support/docview.wss?rss=180&uid=swg21284395 Liberty profile: http://www-01.ibm.com/support/docview.wss?uid=swg21597753 The fix for this APAR is currently targeted for inclusion in fixpacks 8.0.0.10 and 8.5.5.5. Please refer to the recommended updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
